I am interested in configuring psotfix + any related stuff needed for allowing my home system (198.162.1.105) to send email (not concerned if it can receive) to my yahoo/gmail accounts. This is because I would like to set up APEX to send emails, although I know that part is a matter for the APEX forum. But, of course, I have searched for documentation; some sound so simplistic, some rather involved, wouldn't surprise me if there are some variant-specific setup tweaks, which is why I ask here.

Where may I find documentation that will help with the right setup for my needs on this version of OEL? Please do not supply the URL to Google, been there.

well, this offering looked very helpful at the front end, but I've run into a snag, in that my static IP setting 192.168.1.105 does not allow my system to take advantage of DHCP, and tuhs I lose my connection to outside. How can this be addresssed?

Sorry please explain. I have no idea what DHCP or static IP as such has to do with relaying your mail for outgoing connections? If your machine can connect to the Internet, the above should work. If you cannot connect to the Internet with your IP setup, that's a completely different story and needs to be addressed separately. If your service provider gives you an IP address for your router and provides NAT services than any private IP will work as long as you use your DSL router as your TCP/IP gateway.
